I was on a very important conference call, and Molly started barking. It suddenly occurred to me that if Molly couldn't smell the passerby, she wouldn't bark. I rushed (with phone to ear) to my bathroom medicine cabinet and grabbed an old bottle of perfume. Still engaged in the phone conversation with the movie producer on the other end of the line, I sprinted to the door and sprayed several spritzes of perfume in the space along the threshold plate. Viola! Molly sniffed, turned, and strolled back to her bed for a nap. No more stranger smell, no more barking- plus, now my very quite, bark-free quarters smell quite lovely!
